Sorry to be off topic . . . but Just a quick reply. Yes, reveal codes is a wonderful tool! It also reveals a very important advantage of WordPerfect. It has a structure that allows for reveal codes. Neither Word nor OOO does. They use a paragraph formatting where the formatting codes are attached to the paragraph markers. (Word does and I assume ooo does because it seems to format the same way) WordPerfect has a much simpler and more flexible design which works more like html code.
Any way, I don't know the recent market share for WP, but I have been hearing these concerns for years. And yes, it is a concern, but to keep it in perspective: first, as much as I love it, its a product. If it dies, I use something else. I already use ooo most of the time (also abiword and textmaker etc.) because they run native on Linux and I have given up any hope that WP will bring back their Linux version.
Second, The Mac has had a tremendous market share growth over the last two years, they have doubled their market share which is now up to about 7% That is back to where it was in the early 90's. I wouldn't count WP out yet!
